Updated maybe easier to answer-

Hello fellows,

I have not been here in many moons so I hope you all are well.

As hinted in the subject line, I am terrible at math, I can build you a nice set of cabinets or fab a steel car fender for you, even make a decent spreadsheet, but math has never been my strongest skill set. I am 60+ years old now and learning more math is not happening for me at this point

I know many of you fine people on BLF appear to be relatives of Einstein and have provided graphs and calculations etc. for just about all of it related to throw and all that it entails, and that is much appreciated to say the least, but I , sad as it may be , do not understand 85 percent of it.

So all of that being said…

In relation to the “worlds most powerful flashlights” graph/ diagram by Enderman

I have a question…please help me to further understand the example below.

Below are numbers from my arbitrary input into a calculator online at Rapidtables.

I would simply like to know how these numbers relate to the Enderman graph.

If the

Illuminance in lux: = 100 Lx (Input)

Distance in feet

To lit surface : = 30 Ft (Input)

And the Answer

=Luminous intensity

result in candella : = 8361.2736 Cd (result)

Would the light source in this example rank on the enderman graph?

Would the cd result above need to be multiplied by another number to rank on the graph?

Eg. 10, 100, 1000 or some other number?

Any simple response is greatly appreciated, please no complex formulas ,as it will not forward my goal to understanding this idea.

Many thanks
